Abstract
The utility model relates to a special folding arm crane for a wind generating set, relating to the technical field of hoisting equipment and solving the problem of maintenance and hoisting of a large effective cantilever in a narrow space of a fan. The special folding arm crane comprises an electric block and an upright column, wherein the electric block is connected with the upright column through a cantilever beam, the cantilever beam comprises a primary cantilever beam and a secondary cantilever beam, the primary cantilever beam, the secondary cantilever beam and the upright column are connected through a rotary shaft, support plates are arranged at the upper side and the lower side of the joints of the primary cantilever beam and the secondary cantilever beam and the upright column, which are connected through the rotary shaft, and locating pin rolls are arranged at the joints of the primary cantilever beam, the secondary cantilever beam and the upright column and below the rotary shaft. According to the special folding arm crane, a steel frame for supporting a single-girder crane is removed, thus the cost is lowered; and the problem of the large effective cantilever in the small space is solved, the space when the special folding arm crane does not work is released, and a single-girder bridge crane is replaced, thus the self gravity of the whole special folding arm crane is reduced and the cost is lowered.
Description
Technical field
The utility model relates to the weight-lifting equipment technical field, especially relates to the special-purpose lifting appliance of a kind of wind-powered electricity generation maintenance.
Background technology
In the cabin of wind power generating set due to the high-altitude more than 90 meters that mostly operates in remote districts, substantially belong to unmanned or remote monitor and control state, and the blower fan inner structure is complicated, the normal operation that guarantees unit must have corresponding maintenance emergency preplan, weight-lifting equipment is exactly wherein a kind of, although frequency of utilization is lower, must be reliable when needing to use.
Use in existing blower fan cabin commonplace have following several: 1, adopt steelframe of many root posts compositions, set up a single-beam crane at the steelframe top and realize hoisting function, this result formats supports, has increased track owing to having increased the column steelframe, because of from great to blower fan structure increased load, cost is high; 2, adopt fixed pillar type cantilever crane as lifting appliance, the cantilever girder of this equipment is the equipment that can not bend, can work in a three-dimensional zone without any interference.But handling limited space in the high aerial cabin that this equipment is applied to limited space many places interfere can produce some and stay distance.3, adopt an electric block to hang on nacelle top and be used for hanging rising article, the suspension hook of this mode can't move on direction all around, can only realize the action of a direction, and working space is seriously limited.All there is many disadvantages in above-mentioned three kinds of schemes, are the reliability, the expansion working space that improve weight-lifting equipment, and the special-purpose arm-folding crane of new maintenance of fan is the technical matters that needs us to consider.
The utility model content
The purpose of this utility model is: provide a kind of wind power generating set special-purpose arm-folding crane, to overcome the defective of prior art, solve in the blower fan small space, the maintenance lifting problem of large effectively cantilever.
According to above-mentioned purpose, the technical scheme that the utility model adopts is: the special-purpose arm-folding crane of a kind of wind power generating set, comprise electric block and column, electric block is connected with column by cantilever beam, it is characterized in that: described cantilever beam comprises one-level cantilever beam and secondary cantilever beam, is connected by axis of revolution between described one-level cantilever beam and secondary cantilever beam and column.
The upper and lower both sides, junction of described one-level cantilever beam, secondary cantilever beam and column that described axis of revolution connects are provided with stay bearing plate.
The bottom of the junction axis of revolution of described one-level cantilever beam, secondary cantilever beam and column is provided with alignment pin.
Described axis of revolution is provided with swing bearing.
Compared with prior art, advantage of the present utility model and beneficial effect are:
1, the special-purpose arm-folding crane of the utility model blower fan designs for narrow space in the cabin specially, and the allocation and transportation spaces is arbitrarily adjusted according to on-the-spot obstacle; When arm extends, the spatial dimension of allocation and transportation enlarges at double; When not in use, can shrink back by holding arms Free up Memory.Cancel the steelframe of supporting single-beam crane, reduced cost.
2, the special-purpose arm-folding crane of the utility model blower fan, thus solved the problem of large effective cantilever little space in, again discharged space when equipment is not worked, replaced deadweight that mono beam crane in bridge type alleviated complete machine, reduced cost.
Description of drawings
Fig. 1 is that the utility model product embodiments is faced structural representation;
Wherein:
1, electric block 2, secondary cantilever beam 3, axis of revolution 4, swing bearing
5, one-level cantilever beam 6, stay bearing plate 7, column 8, alignment pin.
The specific embodiment
In conjunction with Fig. 1, be the special-purpose arm-folding crane example structure of a kind of wind power generating set of the utility model schematic diagram, it comprises electric block 1, column 7, electric block 1 is connected with column 7 by cantilever beam, it is characterized in that: described cantilever beam comprises one-level cantilever beam 5 and secondary cantilever beam 2, is connected by axis of revolution 3 between described one-level cantilever beam 5 and secondary cantilever beam 2 and column 7; The upper and lower both sides, junction of described one-level cantilever beam 5, secondary cantilever beam 2 and column 7 that described axis of revolution 3 connects are provided with stay bearing plate 6; The bottom of the junction axis of revolution 3 of described one-level cantilever beam 5, secondary cantilever beam 2 and column 7 is provided with alignment pin 8; Described axis of revolution 3 is provided with swing bearing 4.
This folding arm crane is under main structure supports, after by lifting mechanism electric block 1, article being hung in the fan engine room of specified altitude assignment, because space in the cabin is narrower and small, therefore by axis of revolution 3, realize that the two-stage cantilever is the position adjustment of one-level cantilever beam 5, secondary cantilever beam 2, the article of suspension hook and handling are adjusted arbitrarily in limited space, when latched position lifting article, for guaranteeing safety, be locked in alignment pin 8 on stay bearing plate 6 this moment.
